Find the volume of a triangular prism that has a triangular base of 4 and height of 3 with a prism height of 11. note: it is NOT 12 i tried and it was wrong

66

Step-by-step explanation:

This was the formula that I used V=14h √(a+b+c)(b+c−a)(c+a−b)(a+b−c)

Hope this helps! :)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
